The Carrera 30 is the most powerful racing exhaust in the Yasuni range and probably one of the best systems on the market. Perfect torque and enormous power in the upper rpm range make this exhaust a candidate for the pole position at every circuit. Many cones and elaborate exhaust gas flow provide perfect flow for the exhaust gases and minimum weight combined with maximum performance. Yasuni production methods and know-how are used in the GP125 class of the World Championship. The silencer is made completely of stainless steel and carbon. Final assembly of the components is done by means of clamps and gas-tight stainless steel rivets, giving the exhaust a high mechanical strength.
